The short version

  • Each has a real cost: GIMP gPLv3 licence requires derivative works to be open-source and freely distributed; Kotobee interactive EPUB 3 features degrade or disappear in mainstream retail readers, Kindle in particular, so a book built around widgets and quizzes cannot simply be resold through ordinary retail channels later.
  • They diverge on capability: GIMP covers Photo editing, Kotobee covers Interactive EPUB 3.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GIMP

  • GPLv3 licence requires derivative works to be open-source and freely distributed
  • Community-driven development with no commercial support tier
  • No native CMYK support for professional print workflows
  • Ecosystem depends on community plugins and scripts for advanced features

Kotobee

  • Interactive EPUB 3 features degrade or disappear in mainstream retail readers, Kindle in particular, so a book built around widgets and quizzes cannot simply be resold through ordinary retail channels later.
  • Exporting a native app does not remove the app store obligations: you need Apple and Google developer accounts, you handle review submissions, and you own every rejection and update cycle.
  • There is no print workflow at all, so a title that also needs a paperback edition requires a separate layout tool and a duplicated production process.
  • It is a small vendor with a limited partner and integration ecosystem, which is a genuine concern for an institution embedding it in a multi-year curriculum programme.
  • Cloud hosting, DRM and user management are priced separately from the authoring licence, so the recurring cost of delivery, rather than the software purchase, is what the budget has to carry.

Kotobee: Can I sell a Kotobee book on Amazon?

You can sell a stripped-down EPUB, but the interactive content that justified the tool will not render. Treat retail as a separate, simpler edition.

Source
Kotobee: Does Kotobee publish the app to the stores for me?

No. It generates the application; you supply the developer accounts and go through Apple and Google review yourself, including every subsequent update.

Kotobee: Is it suitable for a trade fiction publisher?

No. It is built for education, training and reference material where interactivity and controlled access are the point.
